In Python, how to change text after it's printed?

Question

I have a Python program I am writing and I want it to be able to change text after it is printed. For example, let\'s say I want to print \"hello\" and erase one letter eve

Answer 1

Here's one way to do it.

print 'hello',
sys.stdout.flush()
...
print '\rhell ',
sys.stdout.flush()
...
print '\rhel ',
sys.stdout.flush()

You can probably also get clever with ANSI escapes. Something like

sys.stdout.write('hello')
sys.stdout.flush()
for _ in range(5):
    time.sleep(1)
    sys.stdout.write('\033[D \033[D')
    sys.stdout.flush()
